Why the hell... He knows who she is and what she's doing here and yet.. Is it to keep his pride as a man and not let her leave before you know.. The expected time of the 'deed'. Else rumors would be that he can't hold up for more than a few minutes??
Many thanks

another man that just ignores 1/2 of what the female lead says, at least he didn't molest her being in his room.
